perlbench vs the world (Score:2)
I deliberately tried with the non-benchmark of running the core regression tests, because I was curious about process startup as well as steady-state costs, and found something similar - current
clangis slower than currentgcc. I tried to installgcc-llvmfrom macports, in the hope that that would be a fairer comparison, but the port failed to compile, so I've not (yet) been able to see whether thegccoptimiser via LLVM is better than thangccwithout the LLVM "overhead", and hence isolate the effects ofRe:perlbench vs the world (Score:2)
I also wonder about gcc's new -fcreate-profile/-fuse-profile options. Might be worth a try... But ultimately I think a project like using LLVM has more legs than that one-off optimisation.
